The village and park district of Tinley Park added a $3,700 rental fee to fireworks expenses for irrigation equipment to help water down firework landing sites, according to Park and Recreations Director John Curran.

The 118-head sprinkler draws water from the nearby lake and pumps it to the driest ground. The park district began watering the area at 7 a.m. Monday and will continue to water for 12 hours daily until the firework show.

The dry air and hot temps currently flooding the state could make for combustible grounds and fire departments worry about risks as residents ignite sparklers and smoke bombs or even at-home fireworks, Tinley Park Fire Chief Ken Dunn told the Chicago Tribune.

“It’s just going to get more and more dry as we move into July and August,” said state climatologist Jim Angel.

Though light showers are forecasted for the weekend, the National Weather Service reports scorching temps are expected to rise during upcoming months and little to no rain is predicted to counteract the heat. That forecast would put Illinois further into drought debt.
